Night shift rider Zhou Yan received a midnight order that could not be canceled: seven days later, an unfamiliar work badge was delivered to the No. 17 Freezer on the second basement floor of the funeral home. The recipient turned out to be himself. From then on, every midnight, he would receive "forgotten items" sent to non-existent parts of the city. In order to survive until the time of receipt seven days later, he must abide by four delivery rules and complete the last delivery for those who are being forgotten by the world. And his sister, who has been missing for three years, seems to be deep in these abnormal places, reminding him over and over again: Don't trust yourself seven days later.
